MUD-GUARD FOR VEHICLES.

Specification of Letters Patent.

Patented May 29, 1917.

Application'filed October 6, 1914. Serial No. 865,247?

To allwkom it may concern:

Be it known that I; WinnrAM- HEAP HOL-v LAND,a subject of the King ofGreat Britain and" Ireland, and a resident of Alderley 'Edgeyinthecounty ofChester, England, have invented-new and useful Improve mentsin Mud-Guards for Vehicles, of which the-following is a specification.

This invention relates to improvements in mudguards for the wheels ofmotor and other vehicles which are so constructed and disposed as todeflect outward and laterally mud or dust passing to them from theirwheels. In carryi ng this invention into effect such 'a deflectingmudguard has combined with it a second and following deflecting deviceor element which'interposes or permits the interposition of a str eam'or slice of air 'betweenthemud and dustdeflected by the mudguardand-'the-following part of the vehicle and thus blows or forcessuch'du'st and mud away from such following part." Ina convenient 'formthe mudguard may consist-of a plate=disposed in about a vertical planebehind the upper part of the wheel. This-plate-is'not dis-' posed withits leading face directly across thepath' of' travel; it isdi'sposedwith its inside edge'or edge which is nearer to the foreand aft/centerof the vehicle in ad vanceof its outer or'other edge. It thus acts todeflect outward mud and 'dust flying rearward'from the wheel. The amountof such advance or the angle at which the deflector plate" is inclinedto the line of travel maybe varied; or it maybe adjust able while in useaccording to the conditions of road' sur'face' or speed.

Some slight distance behind the described deflector plate mudguard andabout parallel to it or otherwise disposed-to ef-' feet the same objectis another like or equivalent member which, in conjunction with themudguard serves to deflect outward a slice or streamof airto'comebetweenthe deflected mud and the following part of the car, and act as a padorcushion'to' keep the mud or dust ofi that part of thecan' For examplein some types of car bOdIOS the diverging sides extending from the frontof the bonnet to'the sides of the car may act as such following airdeflectors in connection with the front wheels and guards. To allowaccess of air to the following deflector suflicient space for airpassage should. be left between the inner edge of the deflector mudguardand any adjacent part of the vehicle; I

' Instead of being vertical the deflector mudguard may tilt or curveforwardor backward provided it discharges its function of laterally andoutwardly deflecting andmay also or alternately be curved-transverselyinstead of being straight.

' -The accompanying drawings illustrate how this invention may becarried into efect.-

Figures -1 and '2 represent one form= of them'udguard and itscooperating deflector in side elevation and plan respectively,constructed in accordance with-the principles of the invention.

Figs. 3 and l illustrate an adaptation of my=improvements to a motor carof the present customary form having a curved mudguard, Fig.3 showingthe mudguard and a cooperating air deflectordnside ele'-' vation andFig. 4 showing 'them in horii ontal section-taken along the line w-y ofReferring first to-Figs. 1 and'2. A indicates the body'of-thecar. Aboveand 'extending behind the wheel is a'plateC which is horizontallongitudinally and transversely and J's-formed along its outeredge (oralong both edges if desired)-with a downwardly depending flange D. Belowthe plate O- are shorter horizontal plates E of about the same width asthe plate-C, giving clear air passages between themselves and-betweentheupper 'one and the plate C. These plates formguards whicharesupplementary to plate C. Situated below'the plate C-the under sideof which it touches with its upper edgeand behind the plates E is adeflector mudguardplate F, the inner edge off which is disposed belowthe inner edge of theplate-C and the outer edge of which is belowthe'oute'r: edge of the plate 0. As will be -'seen-'by'a-referonce-toFig. 2' the inneredge of the deflector mudguard plate F is in advance ofits outer edge f along the bo'dy of the vehicle." The plate isvertically disposed.

With such an arrangement and disposition, the mudguard F deflectsoutward all the air which rushes through the spaces between the upperplates E and between the uppermost of such plates and the plate 0 whenthe car is in motion.

To insure that none or as little as possible of this air with its dustor mud shall reach the sides of the body of the car there is combinedwith the mudguard F another deflector plate or surface behind it,similarly disposed and arranged, so that air which passes between thetwo deflectors is interposed as a stream or slice or cushion between theside of the car and the air which is deflected by the leading surface ofthe mudguard F. In the form of car and with the mudguard and accessoriesshown in Figs. 1 and 2 the inclined fore part a of the car acts as thissecond deflector. The mudguard F is arranged about parallel to it, airentering the space between them at a and being discharged at (R.

If desired the forward edge of the plate F may be farther from thesurface a than its rear edge, thus giving a space of constantlydecreasing area between them from the air inlet to the air outlet. Thisadds to the velocity of the air passing between the two deflectors andincreasing the effect of such air in keeping the air deflected by theplate F away from the side of the car.

The mudguard F may be of other form than as shown in Figs. 1 and 2 andmay have combined with itother forms of follow ing deflector; In themodification shown in Figs. 3 and A the plate A is bent down to a curvebehind the wheel. Its rear part is bent outward and rearward asindicated at a. Fig. 4:. In front of the plate A and within it is themudguard F of generally similar form and disposition, but with its inneredge at a greater distance from the plate A than is its outer edge. As.before E, E, indicate short horizontal plates, 0& indicates the airinlet between the plates F and A and a the air outlet.

By placing a board G about horizontally in front of the lower end of themudguard F and thus causing the whole of the dust or the like which isdeflected outward by such guard to pass across the opening between theguard and its following deflector, a much greater proportion of thedeflected dust or the like is kept clear of the following part of thevehicle than if the plate Gr were not used and dust could be deflecteddownward.

The plates E, E, may be omitted from the mudguard.

What I claim is 1. In a mudguard for the wheels of vehicles, ahorizontal mudguard plate above the Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Fatents,

wheel and bent down behind the wheel, this part being bent outward andrearward, a deflector mudguard of similar form and disposition withinthe bent down part of the said horizontal mudguard leaving a spacebetween them which is wider at the inside than at the outside, shorthorizontal plates within the deflector mudguard and an auxiliary plateprojecting about horizontally forward from the lower end of thedeflecting mudguard, substantially as described.

2. A mudguard comprising a guard plate disposed above the wheel andextending downwardly to the rear of the wheel, the inner edge of saidplate being in advance of the outer edge, a deflector plate extendingdownwardly and disposed between said wheel and guard plate, the inneredge of said deflector plate being in advance of its outer edge andarranged in sucha manner as to leave a passage for air between the twosaid plates.

3. A mudguard comprising a guard plate disposed above the wheel, adeflector plate extending downwardly from the said guard plate, theinner edge of the said deflector plate being in advance of the outeredge, said deflector plate being disposed so as to form a passage forthe air between itself and the body of the car in which it is disposed,and an auxiliary plate projecting horizontally forward from the lowerend of the first named downwardly projecting deflector plate.

4:. A mudguard comprising a guard plate disposed above the wheel, adeflector plate extending downwardly from the said uard plate, the inneredge of the said deflector plate being in advance of the outer edge,said deflector plate being disposed so as to form a passage for the airbetween itself and the body of the car in which it is disposed,horizontal plates between the wheel and the downwardly extendingdeflector, and an auxiliary plate projecting horizontally forward fromthe lower end of the first named downwardly projecting deflector plate.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
